Best Site to find Earning dates

Whats the best site that gives reliable earnings announcement dates?

I trade only on technicals but before I enter a trade I like to make sure announcement dates are far away.

I use Yahoo finance and IG index's market info but both miss out some dates and even worse give incorrect dates.

Bloomberg is good but only has diaries. i.e I cannot enter the stock in interest. I have to look at the diary every day which is extremely time consuming

Anyone know of a better site, Would be most grateful

Try this one.

Sorry that one may not allow the type of search you want, here's another may be better for what you want.
